Filed: 1955-01-13
Abstract: 763,759. Furnace doors. RILEY STOKER CORPORATION. Jan. 13, 1955, No. 1058/55. Class 51 (1). In a furnace operating under positive gas pressure an access door with its associated air jet apparatus is so arranged that the door cannot be opened unless the air jets are in operation. In the apparatus shown a frusto-conical shaped furnace opening 13 surrounded by an annular air chamber 15 is adapted to be closed by a circular plate 20 which is formed with a frusto-conical refractory filled flange 22 and is pivotally mounted at 25 on a latching bar 26. At one end the bar is hinged to the furnace wall at 28 whilst at its other end it is formed with a cam surface 30. Air nozzles 17 extend from the chamber 15 into the opening 13 the air to them being controlled by a valve 42 mounted on the furnace wall. The valve is provided with an extension 45 and guard 46 the latter being so cut away as to provide access to the actuating part 43 of the valve. A pin 31, formed as a cylindrical part 32 and a semicylindrical part the latter part being provided with a square extension 40, is accommodated in a bore 33 in the air chamber structure 14 a spring 36 biasing the pin inwardly. The pin is provided, on its semi-cylindrical part, with notches 39 and 41 such that when the air valve 42 is closed and the door closed and securely fastened (see Fig. 4) the valve extension 45 and plate 26 are engaged in the notches 41, 39, respectively, the notch 39 co-operating with the latch cam 30 such that the plate 26 is spring- biased into sealing relationship with the structure 14. The valve guard 46 prevents the pin 31 being rotated-such an operation only being effected by the use of a wrench on the square extension 40-until the guard and extension 45 have been rotated through 90 degrees by turning the air valve actuating part 43-an operation also requiring the employment of a wrench. Rotation of the pin obviously frees the latch 26 from the notch 39.

Abstract: 675,382. Radio receiving systems; frequency modulation. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 18, 1950 [Jan. 25, 1949], No. 1314/50. Class 40 (v). In an A.M. or F.M. receiver the frequency modulation and amplitude modulation of the carrier wave due to interference are both detected and one used to balance out the other. The signal detector or discriminator has in parallel a discriminator or detector circuit for detecting carrier modulation, due to interference, of opposite type to the signal modulation and comprising a differentiating circuit 5, 6 (in an F.M. receiver, as shown) or integrating circuit (in an A.M. receiver, Fig. 3, not shown) and amplifier 7 so that the interference varies equally in amplitude with that in the main circuit as the frequency α varies, where α is the difference in frequency between the carrier and the interfering wave or between the carrier and the noise induced side-bands, respectively. Further the main and auxiliary circuits include phase shifters 8, 9 producing phase shifts of # and # + 90 degrees of constant phase difference compensating the 90 degree phase shift due to the differentiating or integrating circuit, so that the interference voltages are of phase to balance out. To this end the phase shifters 8, 9 may be of the type producing phase shift proportional to the logarithm of the frequency α of the input.
